Welcome to our latest tutorial on fetching and displaying data using Angular 17. This guide is perfect for both beginners and intermediate learners looking to enhance their Angular skills. We’ll dive into the process of fetching data from a live API and displaying it with Angular 17’s latest features.

Getting Started

Before we begin, ensure you have the latest versions of Node.js and Angular CLI installed. To create a new project, open your terminal and execute ng new [your project name]. Once created, open the project in your VS Code editor.

Creating the Angular Project:

ng new my-data-app

Creating a New Component

Angular components are the building blocks of your application. Let’s create a new component named “data display.” In the terminal, use the command ng generate component data-display. For this tutorial, we're focusing on Standalone components, so import this component directly into your app component.

Creating the Component:

ng generate component data-display

Fetching Data from an API

To fetch data, we’ll utilize the HTTP client module. If you’re using standard modules, you might need to add the HTTP client module in your app module. We’ll then inject the HTTP client into our data-display.component.ts using Angular’s inject function. This step is crucial for making API calls.

Data Display Component (TypeScript):

import { Component, OnInit, inject } from '@angular/core';
import { HttpClient } from '@angular/common/http';

selector: 'app-data-display',
templateUrl: './data-display.component.html',
styleUrls: ['./data-display.component.css']
export class DataDisplayComponent implements OnInit {
data: any[] = [];
private httpClient = inject(HttpClient);
constructor() { }
ngOnInit(): void {
private fetchData(): void {
.subscribe((posts: any[]) => {
this.data = posts;
